avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT
...
Libav, for some reason, merged this as a public API function. This will
aid in future merges.
A define is left for backwards compat, just in case some person
used it, since it is in a public header.

all: add _DEFAULT_SOURCE locally wherever needed
...
Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE.
The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros.
This solution is on the lines of the one in commit af1818276e
